Wood floor structure

ABSTRACT

A wood floor structure includes a pad layer composed of a plurality of pads and each pad has at least two taper-shaped protrusions extending from each side thereof. Each pad has a rod extending from a top surface thereof. A plurality of wood strips each have at least one hole defined in a bottom thereof so as to receive said rod in said at least one hole.

FIELD OF THE INVENTION

[0001] The present invention relates to a wood floor structure whichincludes a pad layer and a wood floor layer on the plastic pad layer.The pad layer includes rods extending upward therefrom and each woodstrip of the wood floor layer has holes for receiving the rods.

BACKGROUND OF THE INVENTION

[0002] A conventional wood floor structure generally builds postfootings on the ground and lumber posts extend from the post footings.Lumber girders are supported on the post footings and floor joints arethen supported on the lumber girders. Wood strips are connected witheach other and fixed on the floor joints. These wood strips each have aflange extending from one side of the wood strip and a groove defined inthe other side. The flanges are engaged with the grooves so as to beconnected with each other. It requires two different treatment processesto made the flange and the groove for each wood strip. Once the woodstrips are engaged with each other by receiving the flange of one woodstrip in the groove of the other wood strip, they are difficult toseparate from each other. Besides, it takes a lot time to build thefoundation of the wood floor and because it is empty below the floor,noise is heard when walking on the wood floor.

[0003] The present invention intends to provide a floor structure thatincludes a soft pad layer on the ground and a plurality of rods extendfrom the pad layer, each wood strip has holes defined in a bottomthereof so as to receive the rods therein. The floor structure of thepresent invention is easily to build and convenient to change the waythey are arranged.

SUMMARY OF THE INVENTION

[0004] In accordance with one aspect of the present invention, there isprovided a wood floor structure comprising a pad layer and a floor layerconnected to a top of the pad layer. The pad layer has a plurality ofrods extending from a top surface thereof and each wood strip of thefloor layer has at least one hole defied in a bottom thereof so as toreceive the rod in the at least one hole.

[0005] The object of the present invention is to provide a wood floorstructure that is easily to manufacture and assemble.

[0006] These and further objects, features and advantages of the presentinvention will become more obvious from the following description whentaken in connection with the accompanying drawings which show, forpurposes of illustration only, several embodiments in accordance withthe present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Referring to FIGS. 1 to 3, the wood floor structure in accordancewith the present invention comprises a pad layer 10 and a floor layerwhich is engaged on a top of the pad layer 10. The pad layer 10 iscomposed of a plurality of pads and each pad has taper-shapedprotrusions 11 extending from each side thereof. A taper-shaped recess12 is defined between any two adjacent protrusions 11. The pads areeasily connected with each other by inserting the protrusions 11 of onepad into the recesses 12 of the other pad The pads are made of softmaterial so as to provide a good shock absorbing feature when the floorlayer is engaged on the pad layer 10. Each pad has at least one rod 13extending from a top surface thereof.

[0014] The floor layer is composed of a plurality of wood strips 20 eachhave at least one hole 21 defined in a bottom thereof so as to receivethe rod 13 in the at least one hole 21.

[0015] The pad layer 10 is made of soft material so as to absorbvibration and the manufacture of the wood strips 20 is simple. Theassembling is simple and can be completed within a short period of time.

[0016] FIGS. 4 to 6 respectively show different ways of assembly of thewood strips 20. The wood strips 20 can be positioned by the engagementof the rods 13 and the holes 21 so that they will not slide.

[0017] While we have shown and described various embodiments inaccordance with the present invention, it should be clear to thoseskilled in the art that further embodiments may be made withoutdeparting from the scope and spirit of the present invention.

What is claimed is:
 1. A wood floor structure comprising: a pad layerhaving a plurality of rods extending from a top surface of said padlayer, and a plurality of wood strips each having at least one holedefined in a bottom thereof so as to receive said rod in said at leastone hole.
 2. The floor structure as claimed in claim 1, wherein said padlayer comprises a plurality of pads and each pad has at least twoprotrusions extending from each side thereof.
 3. The floor structure asclaimed in claim 2 wherein said at least two protrusions each aretaper-shaped.
